This is a guide to using my open source xtopdf toolkit to create PDF from text and DBF files (including creating simple PDF e-books)
This guide was initially posted on the original iText site http://itext.ugent.be, Bruno Lowagie's site for his product iText, a Java PDF creation library, in a section about other PDF tools. That site is gone now, so I'm re-posting the guide here (with some edits/updates).
xtopdf is both a set of end-user tools and a library for use by developers, to create PDF from various input formats. This post is for end-users.
The steps are for the Windows platform. The steps for UNIX / Linux platforms are similar in principle but differ in the details.
xtopdf should work with any version of Python 2.x which is >= 2.2. Python 2.7.x is the current version of Python 2.x. I have not tested it yet on Python 3.x. I have tested xtopdf with at least versions 2.2.x through to 2.7.x (for some values of x) and did not come across any issues.
1. Get Python from here:
2. Get Reportlab open source version 1.21 here:
(Don't use ReportLab 2.0 although it is available. I've not tested xtopdf with it.
ReportLab 1.21 is the latest stable version in the version 1 series.)
Install it following the instructions in the README file.
It should be straightforward. The main points to take care of are:
2.1 First, before installing ReportLab, run Python once (you may have to add the directory/folder where Python was installed, say C:\Python27, to your PATH variable first). Once that directory/folder is added to your PATH (preferably via Control Panel), open a DOS prompt.
At this prompt, type:
This should start the Python interpreter. You will get a one or two line message with the Python version, and then the Python interpreter prompt.
2.2. At this prompt, type the following two lines:
This should display a list of all the directories/folders that are in the Python PATH (the environment variable PYTHONPATH - different from the DOS variable PATH) - an internal Python variable that gets set automatically, upon startup of the interpreter, to a set of default directories. This variable is analogous to the DOS PATH variable. In this list of directories, look for "C:\Python27\lib\site-packages" as one of the directories. It should be there by default.
If it is there, then exit the Python interpreter by typing Ctrl-Z and Enter.
3. Now install Reportlab:
Unzip the ReportLab_1_21.tgz file with WinZip, into some folder, say c:\reportlab.
This will create a folder called either:
a) reportlab_1.21 with a folder called reportlab under it
b) just a folder called reportlab.
If a), then move (or copy) the reportlab folder (which is under reportlab_1.21) to under C:\Python27\Lib\site-packages .
If b), then move the reportlab folder to under C:\Python27\Lib\site-packages.
The above steps should make ReportLab work.
An alternative way is to just unzip the reportlab .tgz file into some folder, say, C:\RL, and then create a file called, say, reportlab.pth, which contains just one line - the path to this folder where the extracted contents get stored.e.g. C:\RL\reportlab . Please check that step out (in the ReportLab .tgz file's README file for the exact details).
4. After the above steps, to check that Reportlab works, go to a DOS prompt again, run python again as before, and then at the Python prompt, enter either or both of the following commands (on separate lines):
from reportlab import pdfgen
If either or both of these above commands work (and if there is no error message), it means that Reportlab is properly installed.
5. Now you can install xtopdf.
Get xtopdf here: http://sourceforge.net/projects/xtopdf
After downloading the file, unzip it into a folder, say c:\xtopdf. This will create a folder called xtopdf-1.0 under C:\xtopdf. Go to that folder.
There are many Python programs here with the filename extension ".py".
To run, e.g., WritePDF.py, do this:
python WritePDF.py some_file.txt
where some_file.txt is a text file that you want to convert to PDF.
This will run WritePDF.py and the output will be a PDF file called some_file.pdf.
Try opening it in Adobe Reader.
Similarly try running some more programs:
python DBFReader.py test1.dbf (or test2.dbf or test3.dbf or test4.dbf - all of which are in the package)
This should read the DBF file and display its metadata (file header and field headers) and data records to standard output - the screen.
python DBFToPDF.py test1.dbf test1.pdf
This should do the same as the above (DBFReader.py), except that instead of the output going to the screen, it will go to a file called test1.pdf.
And similarly, try out a few other programs. Most or all of the programs can be run as "python prog_name.py". Some require one or more command-line arguments (all of them require at least one command-line argument, at least an input file).
Be sure to try running this one also, to create PDF e-books from text files:
python PDFBook.py book1.pdf book1.txt
This one reads a list of chapter file names (where each chapter is one .txt file) and corresponding chapter titles, from the 2nd argument book1.txt, and creates a PDF e-book out of all the chapters combined, using the chapter title as the heading for each page.
This is a very quick and simple way of creating simple PDF e-books from a set of chapters, one chapter per text file.
